Filed: 1926-06-08
Abstract: 276,104. Robinson, P. G., Sargent, T., and Strachan & Henshaw, Ltd. June 8, 1926. Paper bags, making.-Paper bags, packets, &c. which are folded by a dipper blade adapted to cooperate with a slot upon a. folding roller, the slot having fixed edges between which the folding is effected, have their folded portion gripped by means which are independent of the folding operation or are out of contact with the bag until the fold has been made. The bag, a transverse portion of which is to be folded over on itself and adhesively secured, is fed on to a roller 1 provided in its surface with a slot 1<a> leading to a recess 1<b> in which is mounted a rock shaft 3<a> adapted to be oscillated by a fixed cam 4 as the roller 1 rotates. Each oscillation presses a resilient gripper or blade 3 forward in an arcuate path against the edge of the slot 1<a>. The roller 1 operates in conjunction with an upper roller having a recess 9 in which is adjustably mounted a folding blade 6 adapted to press the element into the slot 1<a>. In the slot it is gripped by the gripper 3 and retained until it has been drawn past a presser roller 18 formed with a recess 18<a> adapted to register with a line of paste applied to the element and ensure that the pressure is applied on a part or parts other than the pasted part. Paste is supplied from a container 14 to a slowly-rotating roller 11 from which it is removed in progressive lines or zones by a bar 10 mounted on eccentric sheave members 12 so that it may contact with the element prior to the folding operation and with the roller 11 which is spaced from the upper folding roller. The roller 11 and container 14 are mounted in cradles 15 pivoted about a shalt 24 and may be removed from the path 10<a> of the bar 10 by a handle 17 connected to a shaft 15<a> pivoted in the cradles 15 and keyed to an eccentric 16, the bearing 16<a> of which is pivoted to the main frame of the machine. The folded elements are stripped from the roller 1 by wires 19 disposed in slots therein. In a modification, the blade 3 is mounted on a rocking arm or lever pivoted to the roller 1 and the folding blade is integral with the upper roller 11.

IPC: F25D17/02
Filed: 1917-10-17
Abstract: 119,554. Harper, W. A. Oct. 17, 1917. Circulating brine through chambers.-In systems for circulating freezing, chilling, or thawing brine or a mixture through a number of separate circuits or refrigerating-chambers, a distribution header located in a central control room and having compartments for the different-temperature brines and a separate multiple-way valve for each circuit branch is employed. The header may be single or double, and continuous or in sections bolted together. The channels or compartments for the three kinds of brine extend throughout the length of the header, and each valve is set so as to give communication between one, or in some cases two, of these channels, and a circuit branch. A header in which slide valves P, Fig. 7, are employed, is shown in Fig. 1. The valves are placed edge to edge and held between end guides Q. The partition separating the freezing brine channel A and the chilling channel C is formed with ribs G<1> so as to entrap air to insulate the lower channel. The thawing brine may enter the valve chamber and pass direct to the port L of the circuit branch, when a threeported valve is employed, or, as shown in Fig. 7, it may enter a channel E in the cover of the valve chamber and pass into the branch port L through a port K and passage W in the valve. A spring X is fitted in a yoke Z at the back of the valve, which is adjusted by a screwed spindle C<1> having an indicator F<1> movable over a plate E<1> to show the setting. The valve has two closed positions, and one each for freezing, chilling, and thawing, and may also be set for a mixture of freezing and chilling. A plug valve H working in a cage G having a cylindrical exterior and conical interior is shown in Fig. 4, as applied to a single header having a thawing channel E located above the freezing and chilling channels. The setting of the plug is indicated by a pointer Y on a key X, the valve being shown as set for the supply of freezing brine through the branch connexion N. The cage may have a narrow tubular extension into the connexion N, to form an insulating air space between the channels. A double header is shown in Fig. 3. Plug valves H are employed having through passages for thawing brine from back and front channels E to the branch connexions N, X. These channels may be separate from the main body of the header. Thermometers W, Fig. 3, and M, Fig. 1, are fitted in each branch. The inside walls of the channels may be coated with insulating cement or other material.

Title: Improvements in modulated signalling systems particularly applicable to wireless signalling
IPC: H03C1/22
Filed: 1920-06-04
Abstract: 168,660. Lea, N., and Radio Communication Co., Ltd. June 4, 1920. Thermionic modulating systems; thermionic amplifiers and detectors.-In a wireless system, continuous high-frequency oscillations are modulated by separately produced modulating potentials, both sets of potentials being applied to the grid of an amplifying valve, to which grid is also connected a source of negative potential sufficient to keep the anode current substantially zero when the modulating potentials are not applied. Preferably the high-frequency potentials have an amplitude not less than that of the modulations. With reference to the characteristic curve, Fig. 2, the high-frequency oscillations of amplitude A<1> are just sufficient to bring the grid potential to the point R<1> at the bend which should preferably be sharp. A positive modulating potential of amplitude A<3> causes the positive half-cycles A<2> of the oscillations to raise the representative point to a position R<2> on the upwardly-inclined portion of the curve, thus causing the valve to produce an output current which is approximately proportional to the modulating potential. In the application to a wireless telephone transmitter, Fig. 3, high-frequency potentials and microphone potentials are supplied through transformers T', T<2> respectively either in series as shown, or in parallel, in which case means must be provided for preventing mutual short-circuiting. The microphone potentials may be amplified before application to the grid circuit. The steady negative potential may be supplied from a battery B or from the potential drop across the grid-leak of an oscillating valve. In the application to receiving systems the antenna is connected to the grid circuit, and the normal grid potential is varied by a buzzer or other modulator, the modulated waves being passed on to a detector circuit. As an alternative, modulation may be obtained by applying a second set of high-frequency potentials to the grid and interrupting or otherwise modulating these. '
